WOW51900319 error is that the user is no longer connected to the server and this is the most common meaning, according to Blizzard support. World of Warcraft (WoW) is an online game Blizzard developed in 2004. This online multiplayer game offers different quests and missions for which you can get rewards. You can also engage in combat with real players to win the battle.

In 2020, approximately 4.8 million players worldwide play WoW. Since the age of 16, the game has been an active topic of discussion among different generations of gamers. However, the game is not without some technical problems. Some common errors reported by online players are error 132, error 134, and WoW51900319 error.

What causes the WOW51900319 error in World of Warcraft?

Some users also receive error messages such as “Disconnected from World of Warcraft” or “Disconnected with error BLZ51900075”, which means the same thing, that the user has been disconnected from the server.

This is not the only explanation for this bug, as many users have complained that the bug occurs even with a normal internet connection. Blizzard’s support claims that this bug was not too active before the release of WoW Legion.

However, users have a different opinion about WoW51900319 error. Some users believe that the error is due to an increase in network latency, which causes the WoW server to stop immediately when the network becomes unresponsive. Other users believe that this error is due to an increase in graphics per frame. Thus, when a user tries to play WoW with a high frame rate, the Internet connection weakens and cannot keep up with the server due to network latency. In my opinion, WOW should be played on a good gaming laptop since it has a good graphics card.

Using an Ethernet cable

If the WOW51900319 error still appears after trying the above methods, we recommend that you check your Internet connection. This is because, in order to play the game smoothly, you need to have a stable Internet connection. The most important thing is to have a good and stable connection, not a good speed.

Therefore, if your Wi-Fi connection offers good Internet access speed but is not very stable, we recommend that you use an Ethernet cable. These cables not only offer high speeds but also provide excellent security. This means that there will be less latency in the network and therefore fewer dropped connections and non-responses from the WOW servers. Therefore, it will help you get rid of the common WOW51900319 error.

Restoring Winsock

We are all familiar with the different types of operating systems available today. Let’s look at the Windows operating system in context. Today, we have several applications on our computer that help us to make our work easier and organized, Winsock is one of those applications.

With the processing of all data on our computer. Most often, programs use it to access the Internet and perform online actions. However, if you cannot connect to the Wow server, you can use Winsock. In addition, Winsock also reverts to the default settings of the Winsock directory. In this way, sometimes even network problems of users can be solved. Therefore, follow these steps to reset the Winsock configuration:

Step 1: First, you must press the Windows key, and then type “cmd” to open the command prompt on the desktop. Also, make sure you are logged in as an administrator before making any changes.

Step 2: You can also select the “YES” option that appears on the screen when the control panel requests permissions.

Step 3: Now just type “netsh Winsock reset” and then press the Enter key on your keyboard.

Step 4: After completing the previous step, you must restart the computer.

Step 5: Finally, you can run Wow to find out its connection to the main game server.

Standard troubleshooting steps

  • Restart the network devices to ensure that the router is not overloaded with data.
  • Share and update your IP and flash your DNS to resolve any network conflicts.

Clear DNS cache

A DNS server or domain name stores the IP address of a website. All IP addresses of websites visited by users are usually stored in the DNS cache. The presence of Wild Code in DNS domain names can lead to DNS poisoning, which in turn leads to DNS corruption and WOW51900319 error. Therefore, users can clear the DNS cache to get rid of this problem.

Using an Ethernet cable

One of the reasons for the WoW51900319 error in World of Warcraft is that Blizzard has increased network latency requirements. As a result, WoW servers will immediately shut down when they see that their network is unresponsive. So we can use a high-speed Ethernet connection. Wi-Fi is not as good as Ethernet cables because it tends to fluctuate, even when it is of the best quality. Ethernet connections use optical cables. So there is less jitter if the provider is the right one.

In short, Ethernet cables have very low network latency and high speed. This will reduce the number of failures. There will also be no more unwanted behavior. This will fix the WOW51900319 error.

Battle.net has proposed fixes for the WOW51900319 error

Battle.net has its own standard operating procedures for resolving connectivity issues, which we call technical fixes. If you see such an error message, you should first check the @BlizzardCS Twitter feed and the realms status page to see if similar issues have been reported.

For your convenience, below are the detailed steps on the same page. They are as follows:

  1. Check for damage or corruption by restarting the user interface, and then make sure that none of the plug-ins or files are damaged or corrupted.
  2. Restart the network devices to make sure they are not overloaded.
  3. Update system drivers to resolve compatibility issues and errors.
  4. Update your IP address and update your DNS to make sure there are no network conflicts.
